Emitting a huge cloud of smoke from your mouth without much force while smoking out of a hookah. A good rule of thumb for when you have blown a donkey is when you cannot see beyond the huge cloud in front of your face.

Info: Hookahs are notorious for allowing the user to take massive hits that produce a lot of smoke. You will not be able to blow a donkey with a cigarette, nor will you be able to blow donkeys from a pipe. It just doesn't happen.
